While the subject matter and review of Adobe 9 are interesting it would appear that Adobe 9 falls far short of Teamcenter,PLM Express, or other Product Lifecycle Management (PLM) software that it will need to compete with in the engineering / manufacturing sector. Mr. Heller is obviously impressed by fun graphics and bright colors, more so than with actual practical functional deployment of such a software within industry or across a global supplier base. This article is vague at best on the usefulness and compliance with existing standards such as the American Society of Mechanical Engineers (ASME) Y14.41 - 2003 standards for Data Sets and Associativity. As stated in this article to edit the posted model one must detach the model from the .pdf format and make edits then reformat into .pdf for sharing and collaboration. While I'm a fan of the very accessable .pdf format being used to share data across a global company or through a global supplier network, this detaching and reattaching violates the tenants of the Master model philosophy. That philosophy holds that there shall be one model, source of all design and manufacturing data, visible to all, but editable by one. The article is vague as to whether or not anyone can make edits with a copy of your .pdf document and acad software (like your supplier or customer who should not have design rights) or if these edits must be made on a master model and all viewers are automatically updated. Adobe being innteroperable with NX, Catia, or PRO-E software, not just CAD models, would be real innovations for Adobe, and worthy of an article. The article presents Adobe 9 as another possible toy for Management and IT to be distracted with, but in the end pails in comparison with real PLM software. I'm sure it would be useful to a bunch of marketing or sales people who don't need to be accountable for their design data.
